In website administration, understanding how to interact with your database is crucial. This comprehensive guide will walk you through the process of displaying tables in a MySQL database server, a skill that is particularly useful for webmasters and website administrators. We’ll be using a hypothetical WordPress blog as our example, which has been installed and is running smoothly with the following database details:
- Database Name: wp1db
- Database User: wp1user
- Database Password: wp1password
This tutorial is designed to be followed using the terminal or SSH to access your MySQL Database server. You should log in as the user associated with your database, in our case, ‘wp1user’.
To understand the importance of this process, consider the following scenario: you’re managing a WordPress blog, and you need to access specific data stored in your MySQL database. This could be anything from user data to post information. Knowing how to display the tables in your database is the first step towards accessing this data.

Accessing the MySQL Server
To begin, you will need to access your MySQL server. This can be done by entering the following command into your terminal or SSH:
<root@server ~># mysql -u wp1user -p
You will then be prompted to enter your password. Once you’ve done this, you will be welcomed to the MySQL monitor. This is the interface through which you can interact with your MySQL server.
[root@server ~]# mysql -u wp1user -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 198 Server version: 5.0.77 Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
Checking the Server Status
Before proceeding, it’s a good idea to check the status of your server. This can be done by entering the following command:
mysql> status
This will display a variety of information about your server, including the server version, protocol version, connection details, and more.
mysql> status -------------- mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 Connection id: 204 Current database: Current user: wp1user@localhost SSL: Not in use Current pager: stdout Using outfile: '' Using delimiter: ; Server version: 5.0.77 Source distribution Protocol version: 10 Connection: Localhost via UNIX socket Server characterset: latin1 Db characterset: latin1 Client characterset: latin1 Conn. characterset: latin1 UNIX socket: /var/lib/mysql/mysql.sock Uptime: 1 hour 10 min 58 sec Threads: 3 Questions: 3307 Slow queries: 0 Opens: 57 Flush tables: 1 Open tables: 29 Queries per second avg: 0.777 --------------
Selecting the Database
Next, you will need to select the database you wish to work with. In our case, this is ‘wp1db’. This can be done with the following command:
mysql> use wp1db;
Upon entering this command, you will see a message stating that the database has changed. This indicates that you are now working with the ‘wp1db’ database.
Displaying the Tables
Finally, you can display the tables in your database. This can be done with the following command:
mysql> show tables;
Upon entering this command, you will see a list of all the tables in your ‘wp1db’ database. This includes tables for comments, links, options, posts, and more.
mysql> show tables; +-----------------------+ | Tables_in_wp1db | +-----------------------+ | wp_commentmeta | | wp_comments | | wp_links | | wp_options | | wp_postmeta | | wp_posts | | wp_term_relationships | | wp_term_taxonomy | | wp_terms | | wp_usermeta | | wp_users | +-----------------------+ 11 rows in set (0.01 sec)
